To travel on Swiss motorways, road users must purchase and display a vignette(sticker) or face large on the spot fines. You can buy a vignette at most bordercrossings, petrol stations, post offices, by phone (+800 1002 0030) and online. The price of a vignette is currently CHF 40. Euros are only accepted near the border at some Petrol Stations, including the service station just past Basel.
